HILKING-MAGHINE INSTALLATION.

To all whom it may concern:

Be it known that I,'J0HN SIME READ, a citizen of the Dominion of New Z ealand, residing at Eltham, in the Provincial D strict of Taranaki, New Zealand, have 1nvented certain new and useful Improvements in or Relating to Milking-Machinelnstallw tions, (for which I have filed an application in New Zealand, May 21, 1919, No. 41,712,) of which the following is a specification.

This invention relates to milking machine installations and its object is to provide a combination pipe main supporting bracket, pulsator, and tap for controlling the connections of the teat cups with the milklng vacuum and pulsator.

' The inventlon is designed for use with 1nstallations of the class in which separate pipe lines are employed for the purpose of providing the milk main and the pulsat1 n main respectively, as well as for use wit installations having a single pipe line, wherein Vacuum acts for the purpose of assisting in the creation of the necessary pulsations in the outer spaces of the teat cups besides serving to draw oil the milk from the inner spaces thereof.

In both instances, however, eral features of construction the same genare embodied.

The device comprises a back plate formed with one or two pipe clamps thereon, and. provided with a pulsator operating on its upper end, and a tap fitted a 1pc clamp, for the purpose of controlling t e teat cup connections.

Referrin to the accompanying drawing in c onj unction with which the invention will be more particularly described Figure 1 is a side elevation (partly in section) and Fig. 2 a front view of the device, as constructed for use with a two pipe line installation, while Fig. 3 is a side elevation (partly in section) of the device as used in a single pipe line installation.

Figs. 4 and 5 are cross sectional views taken through Z Z and Y Y (Fig. 1) respectively showing the cock plug turned to open both the milk and the pulsation connections, to the teat cups.

Figs. 6 and 7 are similar views to Figs. 4 and 5, but showing the cock plug turned to close both the milk and the pulsation connections.

Figs. 8 and 9 are again similar views to Specification of Letters Patent.

Patented J uly 26, 1921.

Application filed August 26, 1920. Serial No. 406,182.

Figs. 10 and 11 are cross sectional views taken through the lines X X and W W respectively (Fig. 3) showing the cock plug turned to open both the milk and the pulsation connections.

Figs. 12 and 13 aresimilar views to Figs. 10 and 11 but showing the plug turned to close both the milk and the pulsation connections.

Fig. 14 and F1gs.=,10 and 11 but showing the cock plug turned so that the milk connection to the teat cups is opened and the pulsation connection closed.

Fig. 16 is a plan view of the face on which the pulsator slide works, and

Fig. 17 pulsator slide valve.

Referring to Figs. 1, 2 and 4 to 9 of the drawings 1 is the bracket adapted to be secured to a fixture 2 and provided at its upper end with a pipe clamp 3 to receive the vacuum pipe 4.

The portion 5 of the v v clamp 3 is detachable from the bracket, it being secured thereon by inserting the projection 6 in the recess 7 in said bracket, and turning the. pivoted stud 8 into the forked lug 9 and screwing a wing nut 10 on said stud.

The a valve surface 11 through which ports 12 and 13 open the port 12' communicating with the vacuum pipe 4 and the port- 13 with the nipple 14 projecting downward from said portion 5. I

The lower clamp for supporting the milk pipe 28 has a detachable portion 15 integral with which a. tap casing 16 is formed, said portion 15 being secured to the bracket 1 by having a projection 17 to enter a recess 18 in the bracket 1 and a pivoted stud 19 adapted to enter a forked lug 19 on the bracket 1 and take a wing nut 20.

The tap casing 16 is formed with nipples 21, 22 projecting from one side 23 pro ecting from the other side, the latter nipple being connected with the nipple 14 by tubing24.

The plug 25 which works in thecasing contains lower port 27, the latter opening through the side of the plug in the same plane as the passage 26, and also through the bottom 15 are again similar views to portion 5 of the clamp is formed with and a nipple an upper cross passage 26 and a I nipple 21 4o alternately with opening of the plug so as to be in constant communication with the milk pipe 28.

The slide valve 29 reciprocated by the rod 30 on the surface 11 has a recess 31 in its lower side, for the urpose of bridg ng the ports 12,13, and a so has an extension 32 at one end, whereby it is capable of opening the port 13 to atmosphere while 'keepin the port 12' closed.

1 he nipple 21 is adapted to be municationwith the outer or in ator spaces of teat cups, and the nipple 22 with the inner. or milk aces of same.

The handle .25 of the plug 25 is preferably located in the same plane as the (ports in the e in r1ng-.

plug, in order to serve as agui in them to the required positions.

To enable the usual milking operations to be performed by the machine, the plug 25 is turned so that the passage 26 connects the nipple 23 with the 'nipple 21, at the same time-as the port- 27 uts the nipple 22 in communication with t e milk pipe 28.

The slide valve 29 by its reciprocation on the surface 11 connects the port 13 with the port 12' and allows vacuum from the pipe 4 to act in the outer spaces of the teat cups, said port 13" to atmosphere and permitting air to pam into the outer spaces of the teat cups, which to gether with the steady vacuum actingin the milk spaces of the cups, produces the necessary pulsations and the-milk flows into the pi 28. n h y giving the plug 25 a quarter turn in the direction indicated in Figs. 6 and so that the handle 25 will occupy the position shown by the straight arrow (Fig. 6 the can be cut of from the usator simultaneously with the cutting o of the ni pic 22 from the pipe 28.

f the lug 25 is givenan turn in t e same direction as shown in Figs. 8 and 9, so that the handle 25 comes to the position indicated b the straightarrow it will be found that t e ni ple 21 is still cut ofi from the pulsator, w ile the nipple 22, owing to the side opening of the port 27 being elon ted, Willbe put in communi cation with t e milk pipe 28. The latter position of the drawn or flushed through the partsof the through the brac et 1 installation through. which milk passes and which require to be kept thoroughly clean. Referring to the construction illustrated inFigs.-3 and 10 to 15 for use with installation in which only one pipe, the milk pipe 28, is used, the ort 12 (passes downward an has a nipple 34 fitted in its lower end, saidnipple being adapted to be put in communication with the outer or inflator spaces of the teat cups.

The tap casing 16 has in this case a lower nipple 35 projecting from one side, said nipple 35 being connected by tubing 38 with ut in com-' additional half plug 25 enables water to be a. nipple 36projecting downward from the block 37 on which the slide valve. 29 operates, the latter nipple being in communication with the port 13. From the other side of the casing 16 an upper nip le 39 projects this last mentioned nipple eing adapted to be put in communicationwith the milk spaces of the teat cups.

The plug 25 is in this case hollow," its lower end being constantly open to the milk pipe 28. An upper elongated port 40 in the plug is adapted to register with the .nipple 39 at the same time as the lower port 41 re 'sters with the nipple'35.

. ith the plug 25 turned to the position shown in Figs. 3, 10 and 11, the usual milk- ..ing operations canbe carried out, only in this construction-it is-the' rt 12' that is alternately connected wit vacuum and opened to atmo here, the extension 32 on the valve 29 being formed to enable this to be done. The same vacuum from the pipe 28 acts in all of the nipples 39, 35 and 36.

In order to prevent the pomibility of milk being-drawn up to the pulsator by way of the nipple 35 tubing 38 and pulsator nipple 36, a small hole 42 is provided in the extension 32 of the slide valve 29, so that air is admitted to the nipples 35, Mind tubing 38, at the same time as the port 12 is opened to atmosphere by the valve 29.

By giving the plu 25 a quarter turn as before, both of the nipples 39 and 35 can-be cut off from the' ipe 28 (Figs. 12,13) and an additional ha f turn enables the nipple 39 to be maintained in communication with the pipe 28 while the nipple 35 is cut ofi from same.

What I claim and desire to secure 'by- Letters Patent of the United States is 1. In milking machine installations a combination pipe line supporting bracket, pulsator, and milk and pulsator connection controllin tap.
